+# The AzerothCore Database Exporter for Database Squashes
+
+> [!CAUTION]
+> These steps are only for project maintainers who intend to update base files.
+
+## Manual setting updates
+
+Update the settings in `DatabaseExporter.ps1` to reflect your setup by opening it with your preffered text editor.
+
+> [!NOTE]
+> Only update the settings within the SETTINGS block.
+
+These are the default settings:
+```ps

+# SETTINGS                                                                             #

+
+## Description of the tool
+
+This tool updates the base files automatically. Hence, it must run from this directory.
+
+This is how it works step-by-step:
+
+1. Check that all paths look correct.
+2. Accept to continue using the tool.
+3. The tool will delete the `db_auth` `db_characters` `db_world` directories in `..\..\data\sql\base\`
+4. The tool will create the `db_auth` `db_characters` `db_world` directories in `..\..\data\sql\base\`
+5. The tool will export the `db_auth` table into `..\..\data\sql\base\db_auth\`
+6. The tool will export the `db_characters` table into `..\..\data\sql\base\db_characters\`
+7. The tool will export the `db_world` table into `..\..\data\sql\base\db_world\`
+
+## Run the tool
+
+> [!IMPORTANT]
+> This tool CAN NOT be moved outside this directory. If you do it will create files in the wrong places.
+
+1. Make sure you have MySQL installed on your system and that the mysqldump tool is accessible by your PATH system variable. If it is not set you will encounter errors.
+
+    - Go into System Variables
+    - Open the PATH variable
+    - Add the path to your $\MySQL Server\bin\ - e.g. C:\Program Files\MySQL\MySQL Server 8.4\bin\
+
+2. If you haven't run PowerShell scripts before, you'll need to adjust the execution policy.
+
+    - Open PowerShell as an Administrator.
+    - Run the following command to allow running scripts:
+    ```ps
+    Set-ExecutionPolicy RemoteSigned -Scope CurrentUser
+    ```
+    - This allows scripts to run on your system, but they need to be locally created or downloaded from trusted sources.
+
+3. Open PowerShell (PS)
+
+    - Press Win + X and select Windows PowerShell (Admin) / Terminal (Admin)
+
+4. Navigate to the script
+
+    - In PS, use the `cd` command to change the directory
+    ```ps
+    cd "C:\AzerothCore\apps\DatabaseExporter"
+    ```
+
+5. Run the script
+
+    - In PS, run the script
+    ```ps
+    .\DatabaseExporter.ps1
+    ```
+
+6. Follow the instructions given by the tool.
+
+7. Now refer back to the database-squash.md instructions. (Located in ..\..\data\sql\base\)
+
+Completed :)
